A tire recycling company will invest $45 million to set up a 91-employee plant in Natchez.

Delta-Energy Group LLC will produce a carbon black product and fuel oils from scrap tires, selling the carbon black to plastics makers and the oil to chemical makers.

The company will set up operations at the site of the former International Paper plant. The Mississippi Development Authority will give the company $600,000 to help rebuild a rail spur.

It will be the first large-scale plant for Delta-Energy, which is owned by R.J. Lee Group, an industrial laboratory based in Monroeville, Pennsylvania, that developed the recycling technology.

International Paper closed its Natchez mill in 2003, laying off 640 workers.
